Not to be confused with the packaging of free food.
Professor David Edwards of Harvard has created WikiPearl – a soft, water resistant edible membrane made from natural food particles which removes the need for packaging and could dramatically reduce the production of plastic containers.
UK households throw out around 4 million tonnes of food and drink packaging waste per year. WikiPearl are already selling yoghurt, cheese and even ice cream at wholefood stores in the USA.
How does it work?
The “skin” – is composed of natural, edible, biodegradable foods and nutrients which create an electrostatic gel by harnessing interactions between natural food particles, nutritive ions and a polysaccharide.
